` (c1. ,cs2- 285) 6 Claims.

The invention relates to devices ior opening and closing sliding doors and' io'r holding the same in closed position.

The main object of the invention to reduce the' number of parts required in a device oi this type, and to simplify their construction and operation whereby the cost of the device will be reduced and the operation easily elected and the eiiective life of the device prolonged.

Another object oi the invention is to provide automatic take-up of any play between the parts of the device or the structures upon which the parts are mounted. y

These and other detailed objects of the inven-V tion will be' apparent from the following description of a selected embodiment of the invention illustrated in the accompanying drawings in which- Figure 1 is a front elevation oi the device ap`` plied tfo a railway car sliding door and body door post, the device being shown as holding thedoor tightly closed.

Figure 2 is a top View of the device,V the car body and door structure being shown in horizon; tal section approximately on the line '2-2 of Figure 1.

Figure 3 is a horizontal section through the device and is taken on the line 3-3 of Figure 1.

Figure 4 is a vertical section taken on the une lI-d of Figure 1. y

Figure 5 corresponds to Figure l but shows the device in'position to effect an initial opening thrust on the door. y I

Figure 6 is a detail transverse section taken on the line 6 6 of Figure' 45. y A

Figure 7 is similar to Figure 5 but shows the device in position to eiect a terminal closing of the door. p

Figure 8 is a detail transverse section taken on the line 8 8 of Figure 7. Y

'Ihe structure to which the device is applied is shown, for illustrative purposes only, as comprising a car body side wall I, having a Z-bar body door post 2 and a weather seal strip 3, and a sliding door 4 having a front edging Z-bar 5, the flange of which engages strip 3 to limit the closing movement of the door. The doorway threshold is indicated at 6.

An anchor for lock member 'I is xedly secured to door Wall 4 and Z-bar 5 by rivets 8, and includes lugs 9 and I0 projecting outwardly of the door beyond the plane of theouter flange of Z-bar 5. Lug 9 is substantially rectangular. Lug I is substantially cylindrical and is located at a lower level than lug 9 and has a peripheral rim II at its outer end,

The bracket I2 is rigidly secured to body door post 2 and the body wall by rivets i3 and projects outwardly rom the wall beyond the plane of the outer ilange of Z-bar 5 to provide a shallow pocket Ill.

A hasp-lever member I5 has one end It loosely pivoted in pocket I4 by rivet I'I, and the other end i8 of the lever forms a handle or mounting for'an extension (not shown) which may be used as a handle to obtain greater leverage.

Intermediate its ends, hasp-lever l5 is provided with elements for cooperating with lock lugs 9 and I0, respectively. Extending transversely of the length of the lever and facing in opposite directions are cam surfaces I9 and 2D, each ofarcuate contour and adapted to engage, respectively, opposite sides of lug I0. When the door is closed and it is desired to open the same, lever I5 is swung to the position indicated in Figure 5 and cam surface 20 is contacted with the lefthand side of lug I and the lever moved in an anticlockwise direction to initiate opening movement of the door. It is understood that when the initial movement is completed the door is readily moved by direct pullon the same independently of the leverage device.

As the door is closed and it is desired to complete the closing operation, against the friction offered by contacting of elements 3 and 5V and possibly other like elements at the rear of the door (not shown), member I5 is moved to the position shown in Figure 7 with cam surface I5 contacting the righthand side of lug I, whereupon clockwise movement of member I5 will force the door tightly shut.

After the door 'has been closed, member I5 is moved to the position shown in Figure l in which lock lug 9 is inserted through a transverse opening 2i vin member I5.' v

A portion 22 of member I5 adjacentits handle I8 forms a housing for receiving a dog 23 pivoted to the sides oi the housing 22 by a rivet 24. The Swinging end of dog 23 is eccentrically disposed about pivot 2i and forms a cam-like shoulder arranged to engage the righthand face of lug 9 whereby member I5, now functioning as a hasp, is moved to the right and the door is securely retained in its furthermost lefthand position. This interengagement of elements 9 and 23 provides an automatic take-up preventing development of play between any 0i the elements of the device or the relative movable parts on which they are mounted, such as the car wall and door.

Preferably lug 9 is recessed, as indicated at 25, to receive the opposing face of dog 23 so that the Contact transmitting the thrust between ,these members is positioned below the level of dog pivot 2d and below the line extending between pivots H and 2li whereby the thrust tends to move dog 23 into even tighter engagement with lug 9 rather than to release the dog, as would be the tendency under the jolting action of the car if the contact between the dog and the lug were at a higher level. l

Preferably dog 23 has a depending finger 26 which may be struck with a hammer or similar tool to free the hasp and lock from each other when it is desired to release the holding device and open the door. Lug 9 and memberfl are provided with apertures 21 (see Figures!) to`receive the usual Wire seal.

From the above description it will be seen that the single member I5 may be utilized as a lever and as a hasp, and contains'v within itself the dog 23 cooperating with the fixed projection from the door to form an automatic take-up. The parts are few in number and of simplev construction and assembly. The operation is simple and thereis nothing to get out of order in the absence of substantial destruction.

It will be understood that the rigid anchoring device may be mounted upon the car body and the hasp upon the car, door, if desired, or the parts may be mounted upon relatively movable doors such as the main door and auxiliary `door of an automobile type railway car.

The details of the `construction and the manner of the mounting of the members upon the parts which they control may be varied in dif-V ferent ways and exclusive use of such modifications as come within the scope of the claims is contemplated. y. l

Whatis claimed is: Y

1. Ina holding device for a sliding door, a hasp arranged for pivotal mounting upon a door member or a door post member and having a pocket between its ends,4 a latch housed in said pocket and pivoted to the sides thereof, said latch having an arcuate face disposed eccentrically about its pivot, a lockv arranged for mounting upon the other of said `members and y including av lug extending into thewplane of said latch and in position to be contacted thereby with a line-between the pivots of said hasp and latch passing above the level of the pointl of contact between said latch and lug whereby the thrusts between the latter will tend to hold them more securely inV contact with each other rather than to dislodge them from each other.

2. In a holding device for a sliding door, a hasp member, a lock member, said members being arranged for mounting,y respectively, l on relatively movable door anddoor post parts, theV mounting for said hasp member being of a pivotal nature and the mounting for said Vlock member being of a xed nature, a dog pivotally mounted on said hasp member and having a cam face arranged eccentrically about the dog pivot and disposed to contact with an opposing face on said lock member, to move the hasp member and lock member relative to each other in a plane paralleling the plane of the door the line of thrust between said contacting faces being below a line passing between the axes of the pivots of said hasp member and said dog whereby the pressure along said line of thrust holds said dog in contact with said lockt 3. In a door holding hasp of the class described, a body portion having a recess extending transversely through the hasp for receiving l a lug on a part to be engaged by the hasp, the hasp body portion including a downwardly opening housing adjacent to said recess, and a dog in said housing and pivoted to the sides thereof and having a portion extending into said recess to contact the lug received therein to hold the hasp and lug in'locking relation, there being a depending finger on said dog extending below said housing which finger may be struck by a tool exteriorly of the hasp to release said dog from'the lug engaged thereby. y

4. In a holding device for a railway car sliding door, a hasp provided with a pivot pin at one end for mounting upon a door member or a door post member and provided with a handle portion at the otherV end, and provided with a pocket between said portions having top and side walls, a dog housed in said pocket and. pivoted at one end at theend of said pocket nearest saidlhandle portion andat its other end forming a cam ele,- ment disposed eccentrically about its pivot and facing towards said hasp pivot pin, there being a slot extending transversely through said hasp adjacent. the cam `element of said dog, a lool; part arranged for mounting uponthe` otherpf said members and including a lug receivablenin Vsaid slot to be contacted by said cam element as said dogA drops about its pivot on Vthe hasp, theltop wall of said pocket holding said dog against movement out of cam functioning posi: tion, said hasp pivot pin, dogpivot, camlelement and lock lug being Vso arranged tliat` said cam element `automatically takesup playbetween said members as the parts are jostled by the move; ment of the car.v

5. Av device as described in claim 4 in which thehasppocket opens downwardly and the dog therein has a finger projecting through the bottom of the pocket to be engaged manually irre# spective of the position of the dog about its pivot.

6. In a door fastening hasp arranged to be secured to a frame or door part, a body portion having a recess extending transversely` of the length of the hasp and arranged to receivt-Lal lugA on an associated door or frame part, said body portion including a hollow housing adjacent to said recess, and a dog in said'housingl and pivoted to the sides thereof'and having a cam-like shoulder extending intosaidV recess to contact the lug receivedtherein to take up slack between the hasp and lug and prevent movement away from each other of the parts to which they are respectively attached.
